Fig. 3From: Genome-wide identification and expression analysis of the SWEET gene family in daylily (Hemerocallis fulva) and functional analysis of HfSWEET17 in response to cold stressGene structures of HfSWEETs from daylily. The exon–intron structures were analyzed by GSDS (http://gsds.cbi.pku.edu.ch). Exons are represented by green boxes, the upstream and downstream are represented by blue boxes, and introns are represented by black linesBack to article page
